Question

Find the weight of a solid cylinder of radius 10.5 cm and height 60cm if the matrial of the cylinder weighs 5 g per cm3

Answer 1

hey dearie! here is your answer...

Radius =10.5cm
Height=60cm
Volume =πr.sq.h
Volume=22/7×10.5×10.5×60
=12790cm.cube

weight=5×12790
=63950gm
=63.95kg.



hope this will help..and if it does u may Mark as brainliest:)

Answer 2

$\boxed{\boxed{\boxed{\bold{\green{Solution :\longrightarrow}}}}}$

$\bold{For \: \: the \: \: solid \: \: cylinder}$

$\bold{Radius \: (r) = 10.5 \: cm}$

$\bold{Height \: (h) = 60 \: cm}$

$\bold{Volume = 2\pi \: rh} \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:\bold{ =( 2 \times \frac{22}{7} \times 10.5 \times 10.5 \times 60) \: {cm}^{3}} \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \bold{= (22 \times 1.5 \times 10.5 \times 60) \: {cm}^{3} }\\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \bold{= 20790 \: {cm}^{3} }$

$\bold\red{Cost \: \: of \: \: 1 \: {cm}^{3} = 5 \: g} \\ \\ \bold\pink{Cost \: \: of \: \: 20790 \: {cm}^{3} = 20790 \times 5 \: g }\\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:\:\:\:\:\:\:\bold\pink{ = 103950 \: g}$
